ComplexNumericRTable.copyImaginary - create and return a copy of the imaginary values of the current ComplexNumericRTable
|
|
Calling Sequence
|
|
NumericRTable copyImaginary( ) throws MapleException
|
|
|
Description
|
|
|
•
|
The copyImaginary function creates and returns a new NumericRTable that contains the imaginary components of each element of the current ComplexNumericRTable.
|
|
•
|
As RTables do not have unique representations, the returned copy is a different Maple object from the original. Therefore changes to the copy do not affect the original.
